Birth Control Methods01:22

Birth Control Methods

7.3K
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

130
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

Community Based Intervention01:30

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Methods Of Healthcare Delivery System

4.3K
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

Cellular Membranes and Drug Transport01:24

Cellular Membranes and Drug Transport

2.1K
Drugs must traverse multiple biological barriers, such as multi-layered skin, single-layered intestinal epithelium, and the plasma membrane, to reach their target sites within the body. The plasma membrane, a highly structured composite of phospholipids, carbohydrates, and proteins, is the cell's protective boundary, facilitating selective substance exchange.
Phospholipids arrange themselves into a bilayer, with hydrophilic heads oriented outward and hydrophobic tails facing inward.

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

6.5K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Area of Science:

  • Public Health
  • Reproductive Health
  • mHealth

Background:

  • An estimated 225 million women face unmet needs for modern contraception.
  • Mobile phone interventions are effective in other health areas but their impact on contraception use is not well-established.

Purpose of the Study:

  • To assess the effects of mobile phone-based interventions on improving contraception use.

Main Methods:

  • Searched randomized controlled trials (RCTs) from January 1993 to October 2014 across multiple databases.
  • Included RCTs focused on mobile phone interventions for contraception uptake and adherence.
  • Extracted data and calculated risk ratios (RR) and mean differences (MD) with 95% confidence intervals (CIs).

Main Results:

  • Five RCTs met inclusion criteria; no trials were at low risk of bias.
  • One trial showed improved oral contraceptive continuation (RR 1.19).
  • Another trial demonstrated increased post-abortion contraception use (RR 1.39) with voice messages and counselor support.
  • A feasibility trial indicated improved appointment attendance for Depo-Provera (MD -8.60 days).

Conclusions:

  • Limited evidence suggests mobile phone interventions can improve contraception use.
  • Interactive voice messages and counselor support show potential for post-abortion contraception.
  • Text messages may improve oral contraceptive adherence, but cost-effectiveness and long-term effects require further investigation.
